Speech recognition and control in a process support system

Abstract

A voice navigation, command and data entry input system for a decision support and electronic record system including a phoneme identification mechanism for identifying phonemes in a voice input signal and generating phoneme identifiers and a word identification mechanism for identifying and providing words corresponding to the phoneme identifications to the decision support and electronic record system. The system includes individual user phoneme identification libraries and field of use, command/navigation and common vocabulary word libraries. A voice input device generates a voice input signal and includes a plurality of voice input device keys for generating control/navigation input control signals.

1 . A voice navigation, command and data entry input system for a decision support and electronic record system, comprising: 
 a core voice recognition engine, including 
 a phoneme identification mechanism for identifying phonemes appearing in a voice input signal and generating corresponding phoneme identifiers, and  
 a word identification mechanism for identifying and providing words corresponding to the phoneme identifications as an output to the decision support and electronic record system,  
   an individual phoneme identification library associated with the phoneme identification mechanism for storing and providing phoneme identifications corresponding to phonemes characteristic of a voice input signal of a corresponding user, and    word libraries associated with the word identification mechanism for identifying and providing as an output words corresponding to the phoneme identifications wherein the words include at least one of a keystroke, a combination of keystrokes, a sequence of keystrokes, a word, a phrase, a character, a letter, a number, a symbol, a command and an instruction, including 
 a field of use library for storing and providing words specific to the field of use context of the decision support and electronic record system,  
 a command/navigation library for storing and providing keystroke sequences pertaining to navigation through and control of operations of the decision support and electronic record system, and  
 a common vocabulary library for storing and providing common words employed in operations of the decision support and electronic record system.  
   
   
   
       2 . The voice navigation, command and data entry input system for a decision support and electronic record system of  claim 1 , further comprising: 
 a voice input device for generating the voice input signal, including 
 a plurality of voice input device keys for generating control/navigation input control signals for controlling control and navigation functions of the decision support and electronic record system.  
   
   
   
       3 . The voice navigation, command and data entry input system for a decision support and electronic record system of  claim 2 , wherein: 
 at least certain of the control/navigation input control signals from the voice input device keys are provided as control inputs to the word identification mechanism and the command/navigation library includes and provides keystroke sequences corresponding to the control/navigation input control signals and pertaining to navigation through and control of operations of the decision support and electronic record system.    
   
   
       4 . A method for voice navigation, command and data entry input for a decision support and electronic record system, comprising: 
 performing a core voice recognition process, including 
 identifying phonemes appearing in a voice input signal and generating corresponding phoneme identifiers, and  
 identifying and providing output words corresponding to the phoneme identifications as an output to the decision support and electronic record system, wherein  
   the phoneme identifications correspond to phonemes characteristic of a voice input signal of a corresponding user, and    the output words include at least one of a keystroke, a combination of keystrokes, a sequence of keystrokes, a word, a phrase, a character, a letter, a number, a symbol, a command and an instruction, and are selected from one of 
 words specific to the field of use context of the decision support and electronic record system,  
 keystroke sequences pertaining to navigation through and control of operations of the decision support and electronic record system, and  
 common words employed in operations of the decision support and electronic record system.  
   
   
   
       5 . The method for voice navigation, command and data entry input for a decision support and electronic record system of  claim 4 , further comprising the steps of: 
 generating the voice input signal from a voice input device, and 
 generating control/navigation input control signals for controlling control and navigation functions of the decision support and electronic record system from a plurality of voice input device keys.  
   
   
   
       6 . The method for voice navigation, command and data entry input for a decision support and electronic record system of  claim 5 , wherein: 
 the output word identification and providing step further includes 
 providing as output words keystroke sequences corresponding to the control/navigation input control signals and pertaining to navigation through and control of operations of the decision support and electronic record system.
